This lets you see at a glance whether functions such as lighting and wiring are responding properly, without having to connect a complete trailer every time. The tester is intended for 12V systems and is useful when troubleshooting towbar wiring, caravan plugs, bike carriers or trailers. That makes it suitable for both DIY users and workshops that want to locate an electrical fault more quickly. ### Suitable for 7-pin and 13-pin connections This version is suitable for 7-pin and 13-pin connections. This allows you to use it flexibly with different vehicles and trailers, which is especially practical when you work with multiple plug types. In practice, this is useful for: - checking trailer sockets on the vehicle - testing trailer or caravan lighting - quick diagnosis of faults in wiring or contact points - inspecting the electrical connection of bike carriers or other carriers with lighting ### Practical to use for diagnosis A socket tester saves time when tracing electrical problems. You spend less time looking for poor contacts, incorrect wiring or a non-working light function, because you can check the connection more quickly than with a separate test setup. This is especially useful if you regularly work on trailer lighting, towbars or the replacement of plugs and sockets. It is also a handy solution for occasional use to quickly test whether the connection is working before departure. ### Key features The known product features of this tester: - suitable for 12V vehicle systems - can be used on 7-pin and 13-pin connections - developed for checking vehicle and trailer connections - compact tool for diagnosing lighting and wiring ### Use in the garage and everyday use This POWERHAND tester is a good fit for the garage, workshop or service vehicle of anyone who regularly checks trailer plugs and towbar connections. It is suitable for maintenance, quick checks after repairs and checking the electrical connection for daily or recreational use. This helps you work more efficiently when checking trailer electrics and reduces the chance of only discovering a lighting problem on the road. ## Breadcrumbs - [Luggage & Transport](https://www.auto-service.be/en/luggage-transport) -
